Uses of α-oxy(oxo) sulfides and ethers in foodstuffs and flavors for foodstuffs

Abstract

Processes and compositions are described for use in foodstuff flavors and as foodstuff article aroma and taste augmenting and enhancing materials of at least one α-oxy(oxo) sulfide and ether having the structure: ##STR1## wherein X is one of: ##STR2## Z is one of sulfur or oxygen; when R 1 and R 2 are taken separately, R 1 is hydrogen or methyl, and R 2 is methyl; and when R 1 and R 2 are taken together, R 1 and R 2 form phenyl moieties; and Y is one of C 1 -C 4 alkyl, C 3 or C 4 alkenyl, acetyl, methoxycarbonylmethyl, or 1,3-diethylacetonyl. The compounds of our invention are useful in augmenting or enhancing the flavor and aroma nuances of berry flavors, cereal-like flavors, nut flavors, broccoli flavors, onion flavors, citrus flavors (including neroli, bergamot, lime), jasmin flavors, grapefruit flavors, concord grape flavors, blackcurrant flavors, milk caramel flavors (e.g., dulce de leche-like flavors), vegetable flavors, cucumber flavors, celery flavors and spice flavors.
